Still, making streets safer for those on foot has been on the county's radar.

"We have adopted a policy that all new streets have to be complete streets, with sidewalks, street lights and crossings where appropriate," Reichert said.

But they don't plan to add crosswalks or overhead bridges to busy county highways.

"It's always a matter of time and money, how much time we've got and how much money we've got to improve our streets. It's a slow and long process," Reichert said. "While we're doing that, pedestrians need to do their part."

"Those kinds of bridges are very expensive and to build one of those bridges for every mile, that'd be impractical," Watkins said.

Instead, some commissioners say public awareness programs are a better option.

"People who decide to dart across those busy highways, they've got to take more responsibility," Lucas but we've also got to better educate the public>

County officials may consider applying for federal grants that award cities money for improving pedestrian safety, but there are no immediate plans yet.
